Alec Baldwin is not welcome back at MSNBC because of his infamous angry behavior, network insiders say — including complaining that “the air at 30 Rock is too dry.”Sources exclusively tell us that MSNBC chiefs are not exactly falling over themselves to get boisterous Baldwin back in the building. One insider said, “He would only show up at work an hour a week to prep for the show, and when he did turn up, he was in an angry mood, red-faced, and shouting at all the staff. And he said the air at 30 Rock was too dry, it was bad for his voice, he needed a humidifier.” .

Poor, poor Alec, it is so sad that not everyone understands how entitled he is.
